Well there is not a big difference between Java JDK 7, 8. And the tutorials from bucky are the best 'I prefer them' :). But these tutorials are just looking good. I thought let me share this with you guys.

Hey yall im wondering if yall can help me for a bit. Im building a gui circumference and area calculator. I have two extra classes. Three total. One is a Validator class and the other is a Circle class which holds all the calculations. My main class is where I have my gui build. How do I combine the two classes in with the gui class, the gui calculator button is where I would like the code to be to combine the classes. Anyone can help me out that be appreacited. Thank you
